    Research on the Construction of Ecological Protection and Restoration Patterns of County Territorial Space Based on the "Trouble-risk" Cognitive System and the Corresponding Countermeasures

    • 摘要: 识别生态保护修复重点区域并制定差异化整治修复策略,是开展国土空间生态保护修复的前提。然而,相关研究在重点区域识别方面较少考虑自然生态系统与社会经济系统的潜在关联,并且缺乏对生态风险的认知。该研究立足生态系统服务功能保护与修复需求,构建了基于“问题-风险”认知体系的国土空间生态保护修复研究框架。以典型快速城镇化地区为案例区,利用InVEST模型评价研究区生境维持、水源涵养、水土保持和固碳释氧等重要生态系统服务功能,识别服务功能重点保护区和退化修复区;采用景观生态风险评价方法,确定生态系统服务功能退化的风险区,最终提出研究区国土空间生态保护修复总体格局与对策。结果表明:(1)研究区生态系统服务功能空间分布差异明显,部分区域发生显著退化;(2)研究期间生态系统服务功能退化的风险整体较低。2019年研究区较高和高风险区面积占比为7.38%,低风险区面积占比为38.14%,较低风险区面积占比为53.45%;(3)基于研究区国土空间生态保护修复格局,提出差异化策略,如完善现有的保护区规划体系,关注绮山森林公园南侧的耕地景观生态修复,以及加强河流景观风险管理。

       

      Abstract: Identifying critical areas for ecological protection and restoration and forming different remediation and restoration strategies are required for ecological protection and restoration in territorial space. However, the relationship between natural ecosystems and socioeconomic systems was seldom considered in identifying the critical areas. And the ecological risks were seldom investigated. In this study, based on ecosystem services′ protection and restoration needs, a research framework for ecological protection and restoration of territorial space was established with a "trouble-risk" cognitive system. Primary ecosystem services in a typical rapid urbanization area were first evaluated by using the InVEST model, including habitat maintenance, water resource conservation, soil and water conservation, carbon sequestration and oxygen release. The critical areas that requiring protection and the degradation areas that needing remediation were then identified. The degradation risk areas of the ecosystem services were determined by using the landscape ecological risk assessment method. Finally, a comprehensive pattern has been established and a strategy for territorial space ecological protection and restoration in the area is proposed. The conclusions of the study are: (1) The spatial distributions of ecosystem services in the study area were significantly different, and some regions showed significant degradation. (2) The degradation risk of ecosystem service during the study period (2019) was generally low, with which, 7.38% accounted as relatively high-risk and high-risk areas, 38.14% as low-risk areas, and 53.45% as relatively lower-risk areas. (3) Based on the pattern of ecological protection and restoration in the territorial space, differentiated strategies are proposed, including improving the existing reserve planning system, paying attention to the ecological restoration of the cultivated land landscape on the south side of Qishan Forest Park, and strengthening the risk control of river landscapes.
